CHANGE IN THE FUNCTIONAL ABILITIES, AFTER THE INFLUENCE OF MAXIMAL PHYSICAL LOAD IN THE COMPETITION PERIOD IN FEMALE VOLLEYBALL ATHLETES FROM THE REPUBLIC OF KOSOVO

Abstract

Abstract Heart rate and blood lactate concentration are appropriate parameters for assessing the intensity of the effort that players must endure during a match. Athletes, coaches and scientists in the sport have a keen interest in monitoring and measuring the body's adaptations produced as a result of training. For this reason, methods are used that provide reliable information about the athlete's performance during a match or training, intensive training is used to achieve the desired metabolic, cardiovascu- lar and neuromuscular adaptations, in order to increase their physical capacity. The aim of this study was to assess the level and differences of functional abilities in female volleyball players during training in the competition period, through: maximum oxygen consumption (VO2max), calculated by applying the Beep test until dismissal. Heart rate before start of training (HRP) and during max- imum load (HRK), blood lactate level, before training (KLPO) and after maximum load (KLKO). The research was conducted on a stratified sample of three sub-samples of respondents, 20 female volleyball players, members of the three first-ranked teams from the first volleyball league of the Republic of Kosovo. For each variable, the basic descriptive statistical parameters were calculated separately; Arithmetic mean (Mean), standard deviation (SD), lower and upper limit of results (±). To determine the intergroup differences, a multivariate analysis of the variance (MANOVA) and a univariate analysis of the variance (ANOVA) were used to test the differences between arithmetic means for each variable. For determining of the special influence of each variable in creating the differences in the groups a LSD test post hoc analysis was applied. Based on the Wilks' Lambda (0.099) and Raos F-approximation (3,401), a statistically significant difference was found between the three groups in the functional abilities at the level of p = 0.005.
